Astronaut Visits Students in Los Angeles NASA astronaut and former National Football League player, Leland Melvin, brought the thrill of space exploration to students at Elliott Middle School in Pasadena, Calif. Melvin encouraged students to study science and mathematics, and invited them to nominate their teachers for the Educator Astronaut program. The program, which will send teachers into space as fully trained astronauts, requires applications by April 30, 2003. More Educator Astronaut program information NASA Study Finds Solar Trend That Can Change Climate A NASA-funded study finds the amount of solar radiation the Sun emits during times of quiet sunspot activity has increased by nearly .05 percent per decade since the late 1970sa trend that, if sustained, could contribute to climate change. Data from three JPL instruments contributed to the study, which may help climatologists distinguish between solar and man-made influences on climate.

Extractions: Earth-to-Orbit Transportation Bibliography Latest update of Andrew Nowicki's bibliography. LACE SCRAM Nuclear powered aircraft Gun Launch for Orbital Vehicles - Bruce Dunn (January 1995) . A discussion of Gerald Bull and his work on the HARP project. This was an attempt to develop launch systems based on the well known and developed technology of chemical explosive based artillery. JPL Work on Russian Thrusters - JPL Universe (16-Dec-94) . Discusses JPL's tests on the Russian SPT-100 and T-100 (Stationary Plasma Thrusters), and a TAL (Thruster with Anode Layer). The article also discusses NASA and Space Power Inc work on Ion engines. The Lawrence Livermore National Laboratory's Special Studies Program (within The Advanced Technology Program (ATP) of O Division) has examined alternative spacecraft propulsion concepts to meet performance or mission objectives. Laser propulsion concepts have been described for several decades. The laser beam is used to heat a propellant with the energetic expansion driving the craft. A series of ATP devised tests were conducted in which a laser beam was directed at a pusher plate with machined paraboloid dimples. Light was focused by each dimple on a spot behind the plate. The focused beam heated air pockets and the expanding pockets imparted a thrust to the plate. This *concept* provides respectable thrust in the atmosphere. In *space* (vacuum) the dimpled plate is jettisoned to expose a block of solid propellant which is ablated by the laser beam to produce thrust.

Topics of interest include experiments and theories regarding the coupling of gravity and electromagnetism, the quantum vacuum, hyper fast travel, and super luminal quantum effects. Because the propulsion goals are presumably far from fruition, a special emphasis is to identify affordable, near-term, and credible research that could make measurable progress toward these propulsion goals.

Extractions: Center Welcome to the Beginner's Guide to Propulsion What is propulsion? The word is derived from two Latin words: pro meaning before or forwards and pellere meaning to drive. Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction. A gas, or working fluid , is accelerated by the engine, and the reaction to this acceleration produces a force on the engine. A general derivation of the thrust equation shows that the amount of thrust generated depends on the mass flow through the engine and the exit velocity of the gas. Different propulsion systems generate thrust in slightly different ways. We will discuss four principal propulsion systems: the propeller,

Advanced Propulsion Concepts The Editors express their appreciation for the assistance given by members of theAdvanced propulsion Technology Group of JPL in preparation of this notebook http://www.islandone.org/APC/

Extractions: The E.R.P.S. was founded in February of 1993 to gather together interested amateurs to learn about, design, build, and test liquid fuel rocket engines. The group early on decided to concentrate on developing and testing high density storable propellant combinations because they allowed the maximum amount of work to be done with the minimum amount of risk to life and limb. After research and consultations, high density Hydrogen Peroxide (H O ) was selected as the oxidizer of choice, with the intent to combine it with a high-density kerosene such as JP5 or regular Jet-A. Peroxide, when catalyzed, produces steam (2 H O) and pure oxygen (O ) at high temperatures. Peroxide makes a fair mono-propellant when used in concentrations above 95% and there was historical experience (the British 'Black Knight' program of the late 60's and early 70's) to show that respectable performances and capabilities could be developed even at lower concentration when combined with a high density liquid hydrocarbon. The British, however, limited themselves by the catalyst they chose to work with, silver screens. Because the melting point of silver is low (936.93 o C), using peroxide at concentrations above about 85% generates a heat of reaction high enough to melt the silver and thereby reduce and eventually eliminate the "catalyst" from the reaction. The physical properties of the reaction and the type of catalyst used, therefore, limited their performance.

Ion Propulsion - Over 50 Years In The Making return to NASA Science News Space Science News home, ION propulsion. Over50 Years in the Making. An attractive (or repellant) idea for propulsion. http://science.nasa.gov/newhome/headlines/prop06apr99_2.htm

Extractions: Space Science News home April 6, 1999: The ion propulsion system on Deep Space 1 is the culmination of over 50 years of development on electric engine systems in space. Launched on Oct. 24, 1998, Deep Space 1 will be the first spacecraft to actually use ion propulsion to reach another planetary body. Dr. Wernher von Braun, a rocket scientist from Germany, was first introduced to the possibility of electric propulsion in the 1930s, through his mentor, Dr. Hermann Oberth. But von Braun started his career working on chemical propulsion systems. Right: An artist's concept depicts the Deep Space 1 probe with its ion engine operating at full thrust. (Links to
